I just had a basic question in regards to what kind of amplifier I will need for this subwoofer. I am getting an RE Audio SE 12' subwoofer (Dual 2/4 ohm; 600W RMS) and was wondering if this amplifier would be able to do the job:

Kenwood 1800W (900W RMS @ 2 ohm) Monoblock Class D:

Alpine MRP 850 (850W RMS @ 2 ohm) Monoblock Class D:

Phoenix Gold Ryval 1600W (800W RMS @ 2 ohm)

My friend was also telling me to find an amp that slightly overpowers the subwoofer RMS on the 2 ohm rail; so is that what I am looking at here?

So from my selection there; will they work with the subwoofer? Is there also one that is better than the others; I am leaning towards the Alpine simply for the name but the Phoenix looks like the better one for the price.

Thanks in advance.
